[0001] The present invention relates to a vehicle having multiple carriages. Specifically, the present invention relates to a pedal assembly between adjacent carriages and an aisle connection and a vehicle including the same. Background Art
[0002] Rail vehicles such as subways usually have two or more carriages. An aisle connection is usually provided between two adjacent carriages to enable people to move between the two carriages. The pedal assembly is part of the aisle connection and is installed at the lower part of the aisle connection. It is generally arranged to be substantially flush with the floors of adjacent carriages, and is used to cover the hinge part or gap between the two carriages and for people to walk on.
[0003] As the vehicle passes through various road conditions such as turns during actual operation, the pedal assembly will undergo single or combined movements such as rotation, stretching or compression, height exceeding, roll, and nodding, and the movement forms are complex. In order to adapt to such complex movement forms, a three-piece pedal assembly is adopted in the prior art.
[0004] However, for very complex line conditions, such as sections with "difficult curves" having a very small turning radius, this three-piece pedal assembly is still not flexible enough, has insufficient passing ability, cannot achieve the complex movements required by such lines, and is prone to creating gaps between parts of the pedal assembly, thus posing a potential risk of injury to passengers or causing distortion and damage to the pedal assembly.

[0026] The technical solution of the present invention will be further specifically described below through embodiments in combination with the accompanying drawings. The description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general concept of the present invention and should not be construed as a limitation on the present invention.
[0027] In addition, in the following detailed description, for the sake of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments. However, it is obvious that one or more embodiments can also be implemented without these specific details. In other cases, well-known structures and devices are not shown in a graphical manner to simplify the drawings.
[0028] Figure 1 An exemplary plan view of the pedal assembly 100 is shown. This schematic diagram shows a five-piece pedal assembly, that is, the pedal assembly includes five pedals. However, those skilled in the art can understand that although the five-piece pedal assembly is taken as an example for description in the text and the drawings, the number of pedals included in the pedal assembly is not limited to five and can also be more than five.
[0029] As Figure 1-3 shown, as an example of the present invention, a pedal assembly 100 suitable for being arranged between two adjacent compartments of a vehicle is provided. The pedal assembly includes a first pedal 1 and a second pedal 2 (the uppermost and lowermost pedals in Figure 1 ), a third pedal 3 and a fourth pedal 4, and a center pedal 5, which are respectively hinged to the respective end walls of two adjacent compartments; the third pedal 3 is arranged adjacent to the first pedal 1, the fourth pedal 4 is arranged adjacent to the second pedal 2; the center pedal 5 is arranged between the third pedal 3 and the fourth pedal 4; and each two adjacent pedals can move relative to each other.
[0030] In the above example, since the pedal assembly, in addition to the central pedal 5 and the end pedals (i.e., the first pedal 1 and the second pedal 2), also has a third pedal 3 adjacent to the first pedal 1 and a fourth pedal 4 adjacent to the second pedal 2 (and may also include additional pedals in the example of more than five pedals described below), relative movement can be achieved between adjacent pedals, and the area of each pedal is relatively small. Therefore, the movement of each pedal is more flexible, so that it can better follow the turning movements of the front and rear carriages to achieve more complex movements, meeting the movement requirements when the vehicle turns, especially when passing through difficult sections of small-radius curves. When the distance between the end walls of adjacent carriages is reduced, for example, five pedals of the pedal assembly can be retracted and can be stacked into three layers in extreme cases; while when the distance between the end walls of adjacent carriages is expanded, for example, five pedals of the pedal assembly are laid out and opened, expanding the standing area of passengers and avoiding gaps that may cause passengers to fall or be pinched. Therefore, the pedal assembly according to the present invention can adapt to more complex routes and reduce the risk of injury to passengers caused by gaps between parts of the pedal assembly.
[0031] As Figure 2 , 3 shown, the pedal assembly further includes at least two sets of link mechanisms 6 that are spaced apart in the lateral direction of the vehicle; all pedals of the pedal assembly except the first pedal 1 and the second pedal 2 are respectively connected to each of the at least two sets of link mechanisms to be supported and capable of moving relative to adjacent pedals. As Figure 2 , 3 shown, each set of link mechanisms 6 includes a first rod 61, a second rod 62, a third rod 63, a fourth rod 64, a fifth rod 65, and a sixth rod 66, where the first rod 61 and the second rod 62 are hinged and connected to the end wall of one of the carriages at their hinged part; the third rod 63 and the fourth rod 64 are hinged and connected to the end wall of the other carriage at their hinged part; the fifth rod 65 and the sixth rod 66 are hinged at their respective middle positions by a hinge shaft 69, both ends of the fifth rod 65 are respectively hinged to the first rod 61 and the fourth rod 64, and both ends of the sixth rod 66 are respectively hinged to the second rod 62 and the third rod 63, where the hinge shaft 69 is connected to and supports the central pedal 5. In the above structure, the link mechanism 6 forms two parallelogram structures with a common apex angle. The present invention uses such a simple and reliable link mechanism to support each part of the pedal assembly and drive the relevant parts to complete complex movements.
[0032] Exemplarily, as a way in which the third pedal 3 and the fourth pedal 4 are connected to and supported by the link mechanism, each set of link mechanisms 6 further includes a seventh rod 67 and an eighth rod 68. The fifth rod 65 and the sixth rod 66 each include two sub-rods separated at the hinge axis. The two ends of the seventh rod 67 are respectively hinged to the second rod 62 and the sub-rod of the fifth rod 65 opposite to the second rod 62. The two ends of the eighth rod 68 are respectively hinged to the third rod 63 and the sub-rod of the fifth rod 65 opposite to the third rod. The seventh rod 67 is connected to and supports the third pedal 3, and the eighth rod 68 is connected to and supports the fourth pedal 4. With this simple mechanism, the present invention utilizes the characteristics of a parallelogram to drive the movement of the seventh rod 67 and the eighth rod 68, realizing the support for the relevant pedals 3 and 4 and driving the relevant pedals 3 and 4 to achieve the required movement.
[0033] As a way in which the third pedal 3 is connected to and supported by the two link mechanisms to achieve various required movement forms, the seventh rod 67 in one set of link mechanisms is connected to the third pedal 3 in a manner that allows relative sliding therebetween, while the seventh rod 67 in the other set of link mechanisms is connected to the third pedal 3 in a manner that allows relative rotation therebetween. Similarly, as a way in which the fourth pedal 4 is connected to and supported by the two link mechanisms to achieve various required movement forms, the eighth rod 68 in the said set of link mechanisms is connected to the fourth pedal 4 in a manner that allows relative rotation therebetween, while the eighth rod 68 in the other set of link mechanisms is connected to the fourth pedal 4 in a manner that allows relative sliding therebetween.
[0034] Those skilled in the art can understand that although two sets of link mechanisms are described as examples in the text and figures, more than two sets of link mechanisms can also be adopted according to specific situations. In this case, for example, the third pedal 3 can be connected to the seventh rod in one or more sets of link mechanisms in a sliding fit manner, and connected to the seventh rod in other sets of link mechanisms in a rotational fit manner. This also applies to the fourth pedal and other additional pedals.
[0035] As a structural example of the above connection in a sliding manner with each other, this connection structure can be in the form of a guide 71 and a guide block 72. As Figure 2 、 5 shown, a guide groove is formed in the guide 71, and the guide block 72 is at least partially received in the guide groove of the guide and can slide in the guide 71. Figure 2 、 5 shows the form in which the guide 71 is connected to the third pedal 3 and the guide block 72 is connected to the seventh rod 67. However, those skilled in the art can understand that a structure in which the guide block 72 is provided on the third pedal 3 and the guide 71 is provided on the seventh rod 67 can also be adopted.
[0036] It should be noted that the sliding connection between the eighth rod 68 and the fourth pedal 4 can also adopt the structure of this sliding connection. Moreover, the connection between the hinge axis of the fifth rod 65 and the sixth rod 66 and the central pedal 5 can also adopt the above-mentioned sliding connection structure.
[0037] As an example of a structure for connecting in a relatively rotatable manner with each other, a rotational structure of a rotating shaft 74 and a receiving member 73 for receiving the rotating shaft can be adopted. As Figure 2 , 4 shown, a receiving member 73 is provided on the seventh rod 67, which has a cylindrical recess in the middle for receiving the rotating shaft 74 provided on the third pedal 3. The rotating shaft 74 can be at least partially received in the recess in the receiving member and can rotate relative to the receiving member 73, so that the relative rotation between the seventh rod 67 and the third pedal 3 can be realized. Those skilled in the art can understand that the installation positions of the rotating shaft 74 and the receiving member 73 can be interchanged. Moreover, the rotational connection between the eighth rod 68 and the fourth pedal 4 can also adopt the structure of the rotational connection described herein.
[0038] As described above, the pedal assembly 100 may further include more than five pedals. For example, the pedal assembly further includes one or more additional pedals disposed between the central pedal 5 and the third pedal 3, and / or one or more additional pedals disposed between the central pedal 5 and the fourth pedal 4. In this pedal assembly, every two adjacent pedals can move relative to each other. In this example, a more flexible movement of the pedal assembly can be achieved to meet more complex movement requirements. The additional pedals therein can be connected to and supported by additional rods provided on the link mechanism (for example, an additional rod whose two ends are respectively hinged to the second rod 62 of the link mechanism and the sub-rod opposite to the second rod on the fifth rod 65, or an additional rod whose two ends are respectively hinged to the third rod 63 and the sub-rod opposite to the third rod on the fifth rod 65).
[0039] The present invention also relates to a through passage, which includes the pedal assembly as described above. The present invention also relates to a vehicle including at least two carriages, and the vehicle includes the through passage as described above disposed between two adjacent carriages. The through passage and the vehicle thus have the advantages brought by the pedal assembly with the above structure.
[0040] Although some embodiments of the general concept of the present invention have been shown and described, those of ordinary skill in the art will understand that changes can be made to these embodiments without departing from the principles and spirit of the general concept of the present invention. The scope of the present invention is defined by the claims and their equivalents.
